Transcript of B2.5 Enzymes

UnderstandingsEnzymes have an active site to which specific substrates bind.Enzyme catalysis involves molecular motion and the collision of substrates with the active site.Temperature, pH and substrate concentration affect the rate of activity of enzymes. Enzymes can be denatured.Immobilized enzymes are widely used in industry.B2.5 EnzymesLactose IntoleranceWhat is an enzyme?http://glencoe.mcgraw-hill.com/sites/dl/free/0078757150/383930/BL_11.htmlApplicationMethods of production of lactose-free milk and its advantages.SkillsDesign of experiments to test the effect of temperature, pH and substrate concentration on the activity of enzymes.Experimental investigation of a factor affecting enzyme activity.http://www.kscience.co.uk/animations/model.swfProduction of lactose-free milk
